A good map is easier to find – The Arctic Journal

A precise map of Greenland is difficult to find even in this time and age of digital maps. This makes any investment endeavor more costly as maps have to be created before infrastructure planning can begin. Therefore, a project is in the works that uses high-resolution satellite images collected over the time frame of two years. Cartographers are turning them into on-line maps, which will be available, online to the public alongside with the satellite images.

Key Takeaways:

  • Most maps of Greenland today are made using data collected during flyovers in the 1930s and the 1980s. This is a good part of the reason why zooming in on a computerised map leaves you with little more than a place name and perhaps a few contour lines.
  • Rescue services, for example, cannot combine GPS with existing maps, making it more difficult to find people who are lost or stranded somewhere away from a populated place.
  • Danish officials today announced promising initial results of a project using satellites to collect cartographic data faster and more efficiently than has been possible using aeroplanes.

“Satellite images exist, but even though they show details such as homes, roads and even football goals (see the same area as a Google map), a lack of uniformity and the sort of detail cartographers need, means they are of little use in mapmaking.”
